• • page 2 <br />Oct. 2$, 1982 <br />Christian Pit <br />1. abnormal moisture temperature conditions needed for selecting <br />the most adapted individuals; <br />2, the possibility of plant suicide; <br />3. the apparent retardation of invasion by native species as a result <br />of using organic mulches(many natives are excellent nitrogen fixers ; <br />4, the retardation in the establishment of the slow nitrogen cycle as <br />caused by a need to manage nitrogen utilization through the fast <br />nitrogen cycle (the need to manage nitrogen through the fast <br />nitrogen cycle is produced by unbalanced C~N ratios directly <br />caused by the additional carbon derived from the mulch ; <br />$. and the fact that success in past seedings without mulch has been <br />good. <br />However, in recognition of the concerns expressed by the Division of <br />Mined Land Reclamation regarding mulch, Schmidt-Tiago has agreed to increase <br />the amount of the bond in the minor disturbance category ($0 acres from <br />$200 to $$00 per acre. This results in a bond increase of $1$,000 which <br />changes the total from $$$,000 to $70,000. We will also be considering <br />an investigation of the need for mulch at this site, its benefits and <br />detriments, and a cost benefit analysis for the mulch. However, it is <br />our understanding that even though the bond includes mulching, in recognition <br />of the State's desire for mulch, the plan stands unaltered, in recognition of <br />our belief that only south and west facign slopes need mulch. <br />CALCAREOUS L4YERS IN THE SOIL: <br />Although dense calcareous layers are not expected to be encountered on <br />this site, we realize that ceratin places may exhibit them. The species <br />selected are fully capable of withstanding moderately calcareous soils. <br />In places, heavier calcium carbonate Layers could be encountered, although <br />we believe they are unlikely. If a layer of white, calcium carbonate is <br />encountered which exceeds a thickness of 8" then that layer will be separated <br />and spoiled into depressions where it will be covered by at least 18" of <br />soil. That depth of soil would place the calcareous material at approximately <br />its original depth. <br />POND IN PIT # 1: <br />It appears there is a disparity in the concepts produced by the varied <br />meanings of the word pond. By pond, we meant more of a puddle of <br />seeping water producing a wet spot than a pond in the sense of a small <br />lake. Probably, this puddle will fill with dust and silt very rapidly and <br />be gone in a few years. We expect that it will support, through natural <br />invasion, a few cottonwood trees. This will add some variety to a generally <br />bleak landscape as well as habitat for song birds, shade for cattle, and <br />roosts for raptors. <br />What we we wish to emphasize is that this "pond" is not a pond in a <br />lake-like sense and therefore has very little evaporative loss. Impact on any <br />water rights, we believe, would be unmeasurable. <br />
